Now with the team complete, the Kyurangers decide to start their campaign to liberate the universe with Earth. Lucky obtains the Pegasus Kyutama that grants him a special armor. However, he fails to control it and the team takes part in a rather unusual training routine to help him master it as they encounter the powerful Ikargen and Mardakko.

The Kyurangers face a new enemy that restricts birthday celebrations, and Lucky uses a unique Kyutama to call for some special help.

The Kyurangers track down the location of the Ho Kyutama, one of the components of Argo, on Planet Vela, whose people are suffering with the pollution caused by Jark Matter. Meanwhile, Stinger finally comes face to face with his brother.

Stinger and Champ are eager to settle their scores with Scorpio, but he approaches Stinger instead and tells him that he is working inside Jark Matter to kill Don Armage instead. Stinger agrees to listen to him, unaware of his true intentions.

After being brought back to life, Tsurugi Ootori declares that the other Kyurangers had accomplished their duty and must leave the rest to him. However, Lucky and the others refuse to comply.

Tsurugi hijacks a Jark Matter station to declare to the whole universe that he will defeat Don Armage once more. However, when he ends up risking civilians' lives, Lucky loses his patience towards him.

Despite Don Armage was apparently destroyed in the past, the present has not changed at all, and the Kyurangers confront Akyanba to release Naga from her control.

Naga's back on the team and the information he got when he was under Akyanba's control may lead them to Don Armage. However, the Kyurangers also discover, much to their grief, that the Orion is damaged beyond repair, just when Kukuruga, the third of the Fuku Shoguns makes his move.

After liberating Lucky's home planet, the Kyurangers split into two groups again, looking for the means to break into Planet Southern Cross to confront Don Armage, but Shou is starting to feel left out, as Tsurugi has been a better leader than him.

Searching for the Perseus Kyutama, Lucky and his friends encounter Mardakko once again, and discover, much to their surprise, that Doctor Anton is still alive.

The Kyurangers have no clue about Don Armage's whereabouts since their last battle, until they hear of planets exploding mysteriously in the Corvus System and set course there, unaware that Tsurugi is keeping a secret from the others.

The Kyurangers return to Earth to stop Don Armage's plan to destroy the universe, but as Tsurugi's condition worsens, Doctor Anton stands in their way. Anton transform into his monster form and enchant citizen to attack Kyurangers
